METHOD AND APPARATUS FOR INTER PREDICTION

摘要

PURPOSE: A method and an apparatus for inter prediction are determine resolution of motion vectors for prediction of a current block according to the size of the current block which is to be encoded, thereby enhancing motion prediction accuracy of the current block. CONSTITUTION: An information obtaining unit(101) obtains information about the size of a current block. A resolution determining unit(102) determines resolution of motion vectors according to the information about the size of the current block. The resolution determining unit determines the resolution of the motion vectors to be in inverse proportion to the size of the current block. A prediction execution unit(103) generates information about the motion vectors and the differential of the motion vectors of the current block based on the resolution. An inter prediction apparatus generates a differential block of the current block by subtracting candidate regions from the current block.
